At present, there are three mainstream process wheel hubs on the market, low pressure casting wheels, flow formed hub and forging hub. This is main technology on the market at present, and some manufacturers also make gravity wheels. Let's talk about the differences and craftsmanship of these types of wheels.
At present, there are three mainstream process wheel hubs on the market, low pressure casting, flow formed hub and forging hub. This is most of the technology on the market at present, and some manufacturers also make gravity wheels. Let's talk about the differences and craftsmanship of these types of wheels.
Low pressure casting wheels
Low pressure casting is well understood. It is to set the mold, and then pour the molten aluminum into the mold, and then apply a certain pressure to make the internal molecules more compact. This is low pressure casting. is to use this wheel. Because of the high cost performance and good production, the price is also cheap and affordable.
Flow formed wheels
Spinning is actually more complicated processes on low-pressure casting, and they are all produced by low-pressure casting, but the part of the rim is heated while rotating and stamping with a spinning machine, so that the molecular density of the wheel hub and the rim part can be improved. Corresponding rims are more rigid, so many car owners currently choose spinning wheels. Of course, it should be too expensive for forging. Spinning takes an intermediate value between casting and forging, which has both cost-effectiveness and performance. The current price of spinning wheels Also somewhere in between. Likewise, the spun hubs are made of the same A356 cast aluminum as the low pressure cast.
The forged wheel is different from the aluminum used in the above two. It uses 6061 forged aluminum. The rigidity is similar to the difference between the iPhone 13 and iPhone 13 S in previous years. One is bent, and the forged wheel is not only in aluminum and rigid. It has an advantage, and the weight is also the reason why many people choose. Lightweight means lower fuel consumption and better control of the body. The most important thing is that forging supports customization. You can do whatever you like. The engineer draws the drawings according to the requirements, and then mills them on the forged aluminum blank. The first two are not supported. After all, no manufacturer will reopen the mold. This is why forging is more expensive.
